Where to empty?

I've been teaching brass for years and I always end up with puddles on the floor. What do you do about what comes out of your horn?

I tried making my own solution at www.thebrassbuddy.com but it is a few months from reality. It is basically a small container with an absorbent and anti-bacterial (and anti-mildew) sponge. Any feedback is welcome!

I have always just dumped it on the floor and cleaned it up when i was done. sometimes i would put a rag on the floor next to me and dump it on the their and then put the rag in the dirty clothes and wash it later.
